Description of Stellite 12 High Performance Cobalt-based Alloy Rod
Stellite 12 high-performance cobalt-based alloy rods are silver-gray round bars with a mirror-like finish and a smooth, non-greasy feel. Cobalt, chromium, and tungsten are melted in a vacuum furnace to form billets, which are then hot-rolled into rods. Finally, they are cold-drawn or fine-ground to the desired dimensions. Available in diameters ranging from 6 mm to 200 mm, with lengths up to 3 meters possible. Shorter rods can be sawn like sausages, resulting in smooth cuts without the need for secondary processing. With a diameter tolerance of ±0.1 mm, they can be machined directly without worrying about unstable clamping.
Every rod goes through a lathe to be chamfered to ensure safe handling as well as a smooth and scratch-free finish. Since the rods possess a roughness of Ra <= 0.4 μm, the need for re-grinding is minimal, which is efficient. Before shipment, the rods undergo ultrasonic testing, so the uniform internal structure, devoid of pores and cracks, can be confirmed. The rods are then wrapped in plastic film to prevent rusting and subsequently placed into shock-resistant wooden boxes cushioned with foam to prevent damage during long-distance travel. Along with the rods, a certificate detailing the batch number, dimensions, weight, and chemical composition is provided.
Rods can be adjusted to specification. A softer or harder rod is achievable with an 1100℃ tempering, controlled air cooling, oil quenching, and tempering to specification. In a dry environment and stored at room temperature, rusting will only occur after three to five years. In essence, the Stellite 12 alloy can be described as "a highly durable, easily processed alloyed steel bar that excels in wear and heat resistance."
Features of Stellite 12 High Performance Cobalt-based Alloy Rod
• Heat Resistance: Above 800℃, cracking from thermal shock is resisted, and it maintains high hardness and oxidation resistance.
• Corrosion Resistance: High chromium creates a Cr₂O₃ protective layer which prevents corrosive damage from acids, alkalis, salts, and high-temperature sulfur.
• Good Toughness: Due to the cobalt matrix, the material has high impact toughness and is therefore capable of being machined with carbide tools and ground.
• Excellent Weldability/Casting: Is easily hardfaced, thermally sprayed, or cast, and has a low chance of cracking.
Applications of Stellite 12 High Performance Cobalt-based Alloy Rod
• Valves: Overlay welding of valve cores and valve seat sealing surfaces for high-temperature and high-pressure ball valves, gate valves, and globe valves.
• Engines: Diesel engine exhaust valves, gas turbine blade edges, and turbocharger housings.
• Tooling and Molds: Hot shears, hot rolling rollers, injection molding screws, extrusion dies, and crushing blades.
• Petrochemicals: Pump bushings, agitators, slurry nozzles, and wear rings.
• Paper and Food: Paper cutters and food-grade agitator blade wear layers.
